In just over a decade, the power conversion efficiency of metal-halide perovskite solar cells has increased from 3.9% to 25.5%, suggesting this technology might be ready for large-scale exploitation in industrial applications. Photovoltaic devices based on perovskite single crystals are emerging as a viable alternative to polycrystalline materials.
As volatile antisolvent vapors reached the solution and mixed with perovskite solvents, crystals started to form and grew at room temperature. Although bulk crystals synthesized by means of these techniques show superior properties compared to polycrystalline films, they are not always suitable for photovoltaic applications.
Perovskite single crystals are free of grain boundaries, leading to significantly low defect densities, and thus hold promise for high-efficiency photovoltaics. However, the surfaces of perovskite single crystals present a major performance bottleneck because they possess a higher density of traps than the bulk.
In (FAPbI 3) 1−x−y (MAPbBr 3) y (CsPbBr 3) x perovskite single-crystal alloys, the excess of Cs and Br induced a relevant lattice stress that eventually results in detrimental phase separation.
SC PSCs have already demonstrated high PCEs, surpassing those of traditional photovoltaic technologies in some cases. This capability positions them as a potentially superior choice for solar energy generation in the future.
